Knowledge

With our newly-developed turning process High Dynamic Turning, HDT for short, and the dynamic FreeTurn turning tools, we are turning the conventional method of turning completely on its head. All familiar turning operations such as roughing, finishing, contour turning, facing and longitudinal turning can now be completed using just one tool.

The conventional turning processes used until now require a separate tool for every contour. This results in enormous tool costs and long tool changeover times. With High Dynamic Turning (HDT), the dynamic FreeTurn tool utilises the all-round level of freedom provided by the milling spindle. The cutting edge can be changed through rotation about the tool axis, providing you with huge savings on tools and changeover times.

See for yourself. The video shows a direct comparison between conventional turning and turning with HDT & FreeTurn. The result: FreeTurn cuts machining time by 25%

  • Almost all workpiece contours can be machined
  • 40% higher feed rate values
  • Up to 90% fewer empty tool paths
  • Adjustable feed rates during the process
  • Improved surface quality thanks to ideal adjustment
  • The versatility of the FreeTurn means fewer tool changes
  • Fewer tool locations in the machine

Depending on the application, different indexable inserts and holders are available ex stock.

Just like a Monoblock tool, our FreeTurn features a slim shank and a screwed-on indexable insert. 

The  FreeTurn indexable insert  can consist of several different cutting edges. Individual point angles, corner radii, chip breakers, coatings and cutting materials can be combined on a single insert as required. This has the chief benefit that different turning operations can be performed using just one tool.

  • Complete turning with just one tool
  • Huge savings on tool types
  • Significant savings on tool changeover times
  • Indexable inserts with up to three ISO geometries can be used on one holder
  • An indexable insert with multiple cutting edges can consist of different point angles, corner radii, chip breakers, coatings and cutting materials and can be customised for use

Positioning of the FreeTurn tool about various axes, e.g. the milling spindle, makes machining possible from all sides. In addition, the approach angle can also be adjusted during machining, which not only enables dynamic machining of almost any part contour in all directions, but also adjustable feed rates and perfect chip control. 

  • Approach angle can be changed during machining 
  • Adjustable feed rates
  • Perfect chip control
  • Dynamic turning in all directions
  • Pull and push cut

Unlike with conventional turning, the main force occurring (cutting force Fz) is directed through the  tool into the spindle and not into the holder. This guarantees optimised force distribution and reduced downtime
